ABSTRACT

Twelve species and two forms of the genus Porphyra from Korea were examined for morphology, geographical distribution and taxonomic delimitation: P. dentata Kjellman, P. ishigecola Miura, P. katadae Miura, P. koreana Hwang et Lee, p. kuniedae Kurogi, P. lacerata Miura, p. okamurae Ueda, P. pseudolinearis Ueda, P. seriata Kjellman, P. suborbiculata Kjellman f. suborbiculata, P. suborbiculata Kjellman f. latifolia Tanaka, P. tenera Kjellman and P. yezoensis Ueda. Sexuality, features of spermatangial area, presence or absence of microscopic denticulation at margin, discernible prototrichogyne in carpogonium and oblique division in carposporangium, and thickness of thallus were important characters for the discrimination and determination of taxa. The evidences were not enough for P. suborbiculata f. latifolia as an independent from and P. okamurae and P. suborbiculata as separated taxonomic species.

Key words: geographical distribution, morphology, Porphyra, taxonomic delimitation
